Abstract
The present invention provides a planar antenna which has a decreased transmission loss, improved aperture efficiency, increased productivity, and reduced cost when it is used in a high-frequency band such as submillimeter and millimeter wave bands, and which allows multibeam scanning and electronic-beam scanning with a thin, simple structure. According to one aspect of the present invention, the planar antenna includes a planar ground conductor, a plurality of radiating dielectrics arranged in parallel and at established intervals on a surface of the ground conductor, and a plurality of perturbations for radiating an electromagnetic wave. The perturbations each have a given width and are arranged at established intervals on a top surface of each of the plurality of radiating dielectrics along a longitudinal direction thereof, and a feeding section is provided alongside one end of each of the plurality of radiating dielectrics for feeding an electromagnetic wave to respective lines formed by each of the radiating dielectrics and the ground conductor.
